The 37-year-old Duchess of Sussex revealed she and Prince Harry are expecting their first child together this coming spring in a statement from Kensington Palace.

A palace spokesperson confirms to ET that Meghan has passed her 12-week mark of pregnancy and is in “good health.” News that the couple are to be parents comes just moments after they touched down in Sydney, Australia, to embark on a two-week tour of Australia, New Zealand, Fiji, and Tonga.

The tour will continue as planned, despite there being warnings from the Foreign Office of a risk of Zika virus on the islands of Fiji and Tonga. Meghan, however, will not be attending the Fiji War Memorial or the Colo-i-Suva forest, but rather Harry will be visiting those places solo.

"Zika virus infections during pregnancy have been linked to miscarriage and can cause microcephaly, a potentially fatal congenital brain condition," the Mayo Clinic states on their website. "Zika virus also may cause other neurological disorders such as Guillain-Barre syndrome."

According to several royal reporters, the Duchess received medical advice before leaving for the tour.
